Summary

Lighting:•The spaces draw students in while providing a relaxing and open

experience and meeting IESNA and ASHRAE standards.

Daylighting

•The Study Lounge offers quality daylight levels throughout the

day.

Thermal Analysis

•The additional shades reduce the solar load and overall

cooling load of the study lounge.

Electrical

•Direct Coupling is more effective then inverter based

systems.
